Hi Jon,
Robert confirmed your find= ngs and already pushed the changes to another repo (I guess pipelined). Sti= ll figuring out how to sync it with the kirkstone repo. Thanks for your hel= p!

Thanks for the answer Jon,
I must double confirm this then..= . I recall that on kirkstone:
  1. There were no labels in both meta-ti-bsp and meta-yocto-bsp,
  2. They were missing for both dts (black and green).
Will= check this with the author (Robert C Nelson) and also test it tomorrow and= let you know.

Subject Re: [meta-ti] [kirkstone] libgpiod-tools gpioinfo missing for = beaglebone

We can do a little digging to hopefu= lly find out.

Based on my checkout which may be ne= wer or older than yours:
* According to meta-ti/meta-ti-bsp/c= onf/machine/beaglebone.conf, the kernel recipe used is linux-bb.org.
* According to meta-ti/meta-ti-bsp/= recipes-kernel/linux/linux-bb.org_gi= t.bb, the kernel repo used is github.com/beagleboard/linux.git, branch v6.1.46-ti-r13.
* According to that repo, the boneblack should have the gpio-li= ne-names and the bonegreen doesn't...

To find out why yo= u may have to ask them. Or look through the history to find a commit about = it.

1. What could be the cause for that (exact different between Dunfell and Ki= rkstone in meta-ti)? Can it be that the relevant dts file(s) somehow change= d?
The gpio names are defined in the device tree by de= fining "gpio-line-names =3D ..."
2. Aside from labels missing, can there be any other consequences here? I t= ested gpio outputs state changing and it works normally.
I'd guess no, other than it being harder to identify the correct gpio. <= br>

I would appreciate all help and feedback!
